2661540002

Overview

The Fair-Rite Products Corp. part number 2661540002 is a solid, free-hanging round cable ferrite core designed for electromagnetic interference (EMI) suppression. It utilizes Material Grade 61, which provides high impedance characteristics in the 200-1000 MHz frequency range. The component exhibits an impedance of 205 ohms at a test frequency of 100 MHz. Physically, it features an inner diameter of 0.250 inches (6.35 mm), an outer diameter of 0.562 inches (14.28 mm), and a length of 1.125 inches (28.58 mm).

Feature Summary

• Solid construction with a circular cross-section for uniform cable engagement.
• Utilizes Material Grade 61 to deliver effective noise attenuation in high-frequency applications.
• Free-hanging design allows for easy installation over existing cables without disconnection.

Applications

• Suppression of common mode noise on round cables within electronic assemblies.
• Mitigation of electromagnetic interference in radio frequency circuits.
• Noise reduction for data transmission lines operating in the UHF spectrum.

Procurement Notes

Verify that the target cable diameter falls within the specified inner diameter tolerance of 0.250 inches to ensure proper fit and magnetic coupling. Confirm that the application environment does not exceed the thermal limits associated with Ferrite Material Grade 61. Check for RoHS compliance requirements if the end product mandates specific environmental standards. Ensure the physical dimensions align with available space constraints in the final assembly layout.

Selection Notes

Select this component when high-frequency noise suppression above 200 MHz is required. Material Grade 61 is distinct from lower-frequency materials like Grade 43, making it suitable for broadband RF applications. The solid round geometry is preferred over split cores when permanent installation or higher mechanical integrity is needed. Compare impedance curves against specific cable configurations to validate performance before integration.

Part Context

This component belongs to the Fair-Rite Round Cable EMI Suppression Cores series. The numbering system indicates Product Class 26 and Material Grade 61. It is categorized under cable ferrites used for passive noise filtering. The solid design differentiates it from split-core variants, offering a more robust solution for fixed installations where cable removal is not anticipated during maintenance.

Replacement Considerations

Direct substitutes must match the 205 ohm impedance at 100 MHz and Material Grade 61 composition. Alternative Fair-Rite part numbers may offer different physical dimensions while maintaining similar electrical properties. Verify that any replacement maintains the same inner diameter clearance for the specific cable being treated.
